Let's solve a classic problem: generate an invoice and email it as PDF to a client.

Historically I would do it with gem wicked_pdf. But the underlying technology wkhtmltopdf is now Archived!

So, we need to find other solutions.

DocRaptor is an affordable API wrapper around the expensive Prince technology, that gives you a lot of options for rendering and storing PDF.

P.S. In the episode I forgot to mention another powerful feature that I love: generating a PDF from an URL.
P.S.2. Docraptor pricing is per document, not per page!
